Is it better to make the stairs cast-in-place or steel frame?

Cast-in-place stairs are better.

Cast-in-place casting is suitable for building industrialization, which requires mold fixing, that is, assembling the formwork on site, and then pouring concrete.

compared with prefabricated components, prefabricated components are processed by molds in the factory workshop, which is suitable for mass production, that is, building industrialization.

stair size

during stair construction, installers often make mistakes due to one problem: stair size. Because the height in the decoration design drawing is different from that in the building structure drawing, the height in the building structure drawing does not include the thickness of the decorative layer, which needs to be calculated separately.

A stair designer often uses the height of the building structure diagram without considering the height, without calculating the decorative layer, so in order to avoid such mistakes, the decorator should first pop up the height of the decorative layer with ink lines, and then the surveyor needs to re-measure the height.
